What is a modem/router combination?
The modem is a device that allows you to access the Internet by delivering data from your Internet service provider (ISP), whereas the router distributes the Internet connection to several devices in your house or place of business using Ethernet or Wi-Fi connections.
Routers and modems were two different devices in the past. But nowadays, there are cable modem router combos, also called gateways, which provide the convenience of having a modem and a router in one device.
A single device that combines the features of a modem and a router is known as a modem-router combo. It acts as the entry point for that signal, as well as the hub for sharing the Internet signal among the different devices in your network.
What are the factors to consider while purchasing a Xfinity compatible modem/router combination?
Compatibility:
Verify that the modem/router combo is compatible with the Xfinity network. The list of authorized devices is available on the Xfinity website.
DOCSIS Standard:
The highest speed at which your internet connection can operate is determined by the Data Over Cable Service Interface Specification (DOCSIS) standard. As of right now, Xfinity supports both DOCSIS 3.0 and 3.1. Selecting a DOCSIS 3.1 modem/router combo is advised if your internet speed plan allows for greater speeds.
WiFi speed:
It is advised to select a modem/router combo with Wi-Fi 6 (802.11ax) or Wi-Fi 5 (802.11ac) technology if you intend to use Wi-Fi. Compared to Wi-Fi 5, Wi-Fi 6 offers better coverage and faster speeds.
Ethernet ports:
Selecting a modem/router combo with at least 4 Ethernet ports is advised.
Number of Channels:
Your internet connection’s maximum speed is based on the number of channels available. Faster internet speeds are associated with more channels. It is advised to select a modem/router combo that has four upstream and at least sixteen downstream channels.
